Singer in church getting nothing right tries afresh (9)
I believe the answer is:
chorister
'singer' is the definition.
(chorister is a kind of singer)
'church getting nothing right tries afresh' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'getting' says to put letters next to each other.
'nothing' becomes 'o' (looks like zero - 0).
'right' becomes 'r' (common abbreviation).
'afresh' indicates an anagram.
'tries' with letters rearranged gives 'ister'.
'ch'+'o'+'r'+'ister'='CHORISTER'
'in' acts as a link.
(Other definitions for chorister that I've seen before include "Choir member" , "Boy singer" , "Church, cathedral singer" , "Boy in church" , "Choirboy or girl" .)
